Start up issue on 04 GT have to tap gas to keep it running

Air filter was replaced about 5k ago and the car is sitting on 142k. I've owned it for about a year and put about 15k on it. I bought it from a guy I know and not sure if he ever changed the plugs. I'll get on that ASAP.

Ok, since you bought it all you changed was the air filter. If you have not changed the rest (including the trans. filter/fluid) then I would do all that. Whenever I buy or get a used car I always assume that none of this has been done and change it all. Doing this ensures that I know exactly when everything was done and there is no guessing. I never assume the previous owner changed anything on schedule. I'd be willing to bet that those are the original plugs and wires and your plug gap is way off.

Nonetheless, always good to check that there's no rat's nest in there.
